2 Pieces Domestic Sewing Machine Bobbin Cases, 10 Pieces Metal Sewing Machine Bobbins, for Embroidery/Household Sewing Machine/Brother/Singer/Janome/Newhome

I bought these because I needed the bobbins and was reassured that it said they were compatible with most sewing machine types (I use a Janome). I would say 1/2 of the bobbins fit in my machine and the others are unusable.I accidentally used one of the bobbin cases and spent a frustrating morning snarling up my sewing project and wasting thread. Took me ages to realise what I had done - they are now thrown away to prevent me accidentally picking them up and putting them in my machine.A false economy - you won't save money as unfortunately you will have to buy better quality ones all over again.
